You know I've always noticed how little the Sticky Launcher made sense. You reload it not by putting more stickies in, but by moving a lever on the side of it back and forth. I guess that just magically creates more stickies. I guess the green thing on the bottom of it is supposed to be a container but it definitely couldn't hold all 30 or so of them. I think the SL would make a bit more sense if after you use 8 stickies the reload changes to you putting in a new container of 8 more stickies.

Well, one theroy I read suggested that the bombs were in a sort of "deflated" state that took up much less room. Cocking the launcher would trigger the inflation of the bomb's body. Similar to the bombs from that helicopter in Half Life 2.
